A new study comparing pre-roll, mid-roll, and out-stream video ads has revealed that pre-roll ads are by far the most popular among internet users. Viewers find them less intrusive and more memorable than all other video ad formats.

Talking of pre-roll ads, Twitter has announced that it will begin selling pre-roll ads on Periscope videos within Twitter itself. They hope that this will encourage both marketers and video producers to create more exciting and engaging video content.

With Facebook hot on their heels, Snapchat is working hard to keep marketers on their side. After acquiring a new media license, they have now made it much easier for marketers to purchase full-screen ads by including the format in their self-serve advertising options.

The ability to live stream directly to a YouTube channel from mobile devices was previously limited to accounts with 10,000 or more subscribers. This month, YouTube revealed that this feature is now available to channels with 1,000 subscribers or more.

Facebook is looking to stay ahead of the live video game by testing a brand new feature: native split-screen, two-person broadcasts. Currently, this feature is limited to personal profiles on Facebook’s iPhone app, but it’s likely to be expanded in the near future.
